Looks like you already see the "code" attribute information. See also

I don't understand why you think that en-US QUERTY keyboard layout is 
useful in any locale...

I think that .char should be useful value for implementing text editor 
implemented with <canvas> and DOM. For example, if Ctrl+C is pressed, 
then, if .char is empty value, it lets web developers know the key 
combination isn't inputting text. Otherwise, they cannot know the fact 
because even on Windows, some keyboard layout uses Ctrl key for 
inputting text.

As I mentioned, non-alphabet input keys like punctuations or non-Latin 
keyboard layout, I believe it's not useful the value without Shift key 
state since it's impossible web developers cannot know the shifted key 
value.
